Abstract
Disclosed herein is a system for recovering flash gas from an oil storage tank. In one example of the invention, the system may include a flexible storage tank that receives the flash gas and temporarily stores the flash gas; a compressor having an input receiving the flash gas from the flexible storage tank, the compressor compressing the flash gas to form compressed gas; and an oxygen reduction subsystem receiving the compressed gas, the oxygen reduction subsystem reducing an amount of oxygen from the compressed gas. In this manner, the resulting compressed oxygen-reduced gas that has been recovered can be injected into a sales gas line for use, under certain conditions.
